Overview This machine is used for PVC Pipe extrusion production line, PVC formula is expected by feedscrews metered barrel, the material through the screw conveyor, compression, plastics, metrology, enter mold. The machine screw and barrel are made 38CrMoAlA, after forging, quenching, two aging, nitriding treatment. The difference with other manufacturers is: SCREW rough edge after quenching, hardenability excellent screw pu double pipe extrusion line, but by the amount of aging at twice the effective elimination of stress. Meanwhile sophisticated processing, screw segments spiral edge phase error is small. Barrel and screw interchangeable. For different materials double pipe extrusion line configuration, the screw structure is all changing. Reduction gear box distribution box are hard surface structure, high precision, anti-fatigue. Gear box gear made of 20CrMnTiA, carburizing tooth grinding, helical gear distribution box made of 38CrMoAlA, by CNC hobbing forming, nitrogen treatment. A2, ZDT40 sizing box 1, the main parameters: sizing box length: (m) 5.6 adjusting the vertical height: (mm) 80 or so to adjust the distance: (mm) before and after 50 moves the distance: (mm) 1000 pump power (kw) 2.2 × 2 Pump Power: (kw) 3 × 2 sizing range: (mm) Φ16-40 color co-extrusion machine color tube extrusion lines - process: two different materials, extrusion host ------ coextrusion ------- ------ mold cooling setting means synchronous traction machine ------ cutter or rolling screw structure optimization based on material properties and design; suitable for PE, PP, PS, ABS, PET, PC, POM, PMMA, PVC, EVA and so on two different materials or the same material in different colors co-extrusion molding; give full play to the unique dual-curing all kinds of plastic pipe extrusion line, making composite materials should play a leading role; a variety of materials can be integrally molded together technology, goes without adhesive or bonding, it is high efficiency and low cost; the hard materials and soft materials composite, set strength and flexibility in . one of the porous material and a dense composite material to form lightweight high strength material, given its specific properties; may constitute varieties, new tricks, excellent performance of various profiles of double-pipe extrusion line manufacturer, to meet the special occasions. Screw barrel material: high-strength alloy nitride (38CrMoALA) or high-strength quenched alloy (9Cr18MoV); screw length of 20 to 38, depending on the material and product features to be; host driven by imports of goods into the inverter or servo motor; import dual digital display PID regulator digital temperature controller; cylinder 4-zone heating and forced air cooling, depending on the material properties can be used with a copper heat sink to ensure the cooling effect; pu double pipe extrusion line, double pipe extrusion Xinjiang production line, with three presses provided by Qingdao Tongsan Plastic Machinery Co., Qingdao Tongsan Plastic Machinery Co., Ltd. (www.tongsansuji.com) strong, credible, in other industries in Qingdao, Shandong accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead with three presses into the brilliant and you work for a better future!
